From: Giuseppe Ciaccio <[EMAIL PROTECTED]> Date: Fri, 3 Feb 2006 13:02:59 +0100 (CET) To: [email protected] Subject: [Beowulf] new release of GAMMA: x86-64 + PRO/1000 Hello, I'm glad to announce that GAMMA has been ported to x86-64 CPU architecture :-) This release of GAMMA has been tested on a GigEth cluster of dual-Xeon (32-bit) as well as a cluster of single-EM64T (courtesy of OpenCFD, Ltd). So, we lack (and need!) tests on GigEth cluster of dual-processor x86-64 machines (we have no such hardware on site). A new, 64-bit capable, version of MPI/GAMMA has been released as well. GAMMA only supports the Intel PRO/1000 Gigabit Ethernet NIC (e1000 driver). Latency at MPI level is below 12 usec, switch included (6.5 usec back-to-back). No significant difference between 32-bit and 64-bit. More details at the GAMMA web page, http://www.disi.unige.it Some tests on computational fluid dynamics jobs (courtesy of OpenCFD, Ltd) show a very interesting comparison between MPI/GAMMA and LAM. I will post more details on the GAMMA web page soon. A question: Does it still make sense to have a low-latency communication library for Gigabit Ethernet?
